ISIDOR E1. JACOBS, OF KANSAS CITY,

ASSIGNOES T0 TRUCK, TRACTOR, JEESSOURI, A CORPORATION 05 TEETER TOTTEPJ.

Application filed July 12, 1920.

To all whom it may concern:

Be it known that we, Tsrnon M. Jnoons and /VILLIAM CRAMER, citizens ofthe United States, residing, respectively, at the city of Kansas City,in the county of Jackson and State of Missouri, and at the city of St.Louis, State of Missouri, have invented cer tain new and usefulImprovements in Teeter Totters, of which the following is aspecification.

This invention is a teeter-totter and is so constructed as to permitsimultaneous rotation and seesawing.

Its especial advantages are simplicity of construction, durability, andcheapness of manufacture.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts whereever they occur,

Figure 1 is a top plan view;

Figure 2 is a side elevation;

Figure 3 is a sectional view on the line 33 in Figure 1; and

Figure 4: is a sectional view on the line 1 1 in Figure 1.

The beam 1 is composed of a pair ofbowed members 2, the ends of whichare socketed in cleats 3 fastened to the underneath side of seats 1.Seats 1 are preferably shaped more or less like bicycle seats and may besuch, in fact, or mere wooden members.

The handles 5 are attached by screws 6 to the top of members 2, and areprovided with rounded and smoothed handholds 7.

The members 2 are attached by bolts 8 to castings 9, which are piercedby holes 10, through which passes shaft 11. Thus, the teeter-totter ispivoted on shaft 11 and adapted to rock thereon in seesaw fashion.

The diameter of shaft 11 is reduced at its 1 havingthe arms 22, whichare pierced by holes 23, through which passes shaft 11.,

Specification of Letters L?-' ..tent.

Serial at. 395,667.

Table 16 will be supported by legs 24 or any other suitable means.

Thus, it is seen that the beam 1 is adapted to teeter on the shaft 11and to rotate on the kingbolt 17, so as to have a simultaneous seesawingand rotary motion. The said rotary motion may be either clockwise oranti-clockwise. I

Ehaft 11 constitutes a unitary connection for the beam, both for theteeter and rotary motion. The same remark is true, also, of casting 18.Casting 18 connects the beam 1 to the base or table 16 in a mannerpermitting both rotary and seesaw motion simultaneously. So, also, doesshaft 11. The two combined do so also.

The handles 5 assist in bracing the structure composing the beam 1 andcomprising the bowed members 2.

Having thus described this invention, we hereby reserve the benefit ofall changes in form, arrangement, order, or use of parts, as it isevident that many minor changes may be made therein without departingfrom the spirit of this invention or the scope of the following claims.

We claim:

1. The combination of a base, a kingbolt, a rotatable casting fastenedto the said base by the said kingbolt, the said base having a groove, ashaft passing through the said casting, wheels mounted thereon andadapted to run in the said groove, a pair of castings through which thesaid shaft passes, and a beam attached to the said last-mentionedcastings.

2. A. seesaw comprising a base, a rotatable support thereon, said basehaving an annular groove in its upper surface, a shaft journaled in saidsupport, a beam pivoted to the shaft, and wheels carried by the shaftarranged to travelin saio. groove and adapted to partly sustain theweight of the beam.

A seesaw comprising a base, a rotatable support thereon presentingspaced arms, a shaft journaled in said arms with the ends of the shaftprojecting, wheels mounted on the projecting ends of the shaft arrangedto travel on the base, and a beam pivotally connected to the shaft atpoints on the latter, located between the wheels and the arms of saidsupport.

at. A. seesaw comprising a base, a rotae Aug. 15, 1922.

the shaft between said wheels and assisting the latter in sustaining theweight of the beam.

6. A device as described in the preoeeding 5 ehtiin in which the saidmeans consists of a U-shuped member rotatable on the base and receivingthe shaft through the arms thereof.

In testimony whereof we hereunto affix our signatures.
